Abstract:Package managers are legion. Every programming language and operating system has its own solution, each with subtly different semantics for dependency resolution. This fragmentation prevents multilingual projects from expressing precise dependencies across language ecosystems; it leaves external system and hardware dependencies implicit and unversioned; it obscures security vulnerabilities that lie in the full dependency graph. We present the \textit{Package Calculus}, a formalism for dependency resolution that unifies the core semantics of diverse package managers. Through a series of formal reductions, we show how this core is expressive enough to model the diversity that real-world package managers employ in their dependency expression languages. By using the Package Calculus as the intermediate representation of dependencies, we enable translation between distinct package managers and resolution across ecosystems.
北美市场是全球XR产业的核心阵地之一。尽管当下Meta仍然处于领先位置，但竞争格局正在发生变化。2025年5月，谷歌在其开发者大会上正式发布与XREAL联合打造的AR眼镜——Project Aura；在12月的The Android Show大会上，谷歌正式揭晓了Project Aura项目及其背后的Android XR系统关键细节。这一发布不仅标志着谷歌在XR与AI融合领域迈出了关键一步，更意味着其旗舰AI模型Gemini首次真正拥有了“看见世界”的能力，加速Android XR生态在消费级与企业级市场的落地与普及。
